Users are informed that a minor update on Sentinel-2 L2A products is going to be implemented to optimise the encoding of the quality bands (SCL, CLD, SNW, PVI, TCI) over 8 bits instead of 16 bits, in line with the Sentinel-2 L1C products.

All L2A products generated as of 19 September 2018 will feature this small change which is compliant to the SNAP software tool.

Infrastructure maintenance activities on Tuesday 18 and Wednesday 19 September

17 Sep 2018

Infrastructure maintenance activities are scheduled on:

Tuesday, 18 September 2018

Wednesday, 19 September 2018

The maintenance will affect the Data Hub Services according to the following schedule:

The availability in the Data Hubs of several Sentinel-2 L2A products with sensing date between 27 August and 11 September has been delayed due to a combination of contingencies at ground segment level.

The issue has been solved today, 11 September and the recovery of the missing products is ongoing and is expected to be completed by tomorrow 12 September.

Activation of Long Term Archive (LTA) Access

10 Sep 2018

Following the recent upgrades to the Data Hub dissemination points we are pleased to announce that the Long Term Archive (LTA) Access interfaces are ready to be operated, part of the nominal regime to ensure the continued access to all Sentinel Data at all time. As planned, the operations of the data dissemination will soon implement the roll-out of the oldest data from the online access and activation of the interfaces to allow to restore access to historic data from the Long Term Archive (LTA).
The Data Hub dissemination system continues to provide the unified access to all Sentinel Data: the catalogue will continue to publish all data, the discovery and download interfaces (both the graphical user interface and API) provide additional status information to indicate whether the product are online or offline.
Access to the product URL for data that are no longer available online will automatically trigger the retrieval of the data from the LTA, the actual download may be initiated once the data are restored (within minutes to hours). Full details are available in the updated User Guides.

Roll-out of the data will start with the oldest Sentinel-1 RAW data and then will proceed to the other Sentinel product types according to the production volumes and usage patterns.

At least the latest year of Sentinel data will be kept online at all times. The retention period for the various different product types will be tuned according to the usage patterns to ensure efficient access to the most recent and frequently downloaded data, the precise retention period (always greater than one year) is subject to change according to the operational experience.

S3A Data Unavailability on 5 September 2018

06 Sep 2018

Due to a major Sentinel-3A Ground Segment anomaly all L1 and L2 NRT OLC, SLSTR and SRAL user products from sensing time 05-09-2018 19:30 to 06-09-2018 06:06 UTC are missing.

Investigation on root cause is on-going

Sentinel 3A Data Unavailability on 29 August 2018

05 Sep 2018

Due to a planned spacecraft manoeuvre on Sentinel-3A on 29 August 2018 all NRT/NTC/STC OLCI and SRAL user products could be degraded from sensing time 07:38 to 08:13 UTC. NRT/NTC SLSTR user products could be degraded from sensing time 07:38 to 08:47 UTC.

As a consequence of a ground segment anomaly, the availability in the Data Hubs of several Sentinel-2 L1C products with sensing date between 29 and 31 August is delayed.
The anomaly has been solved and the recovery of the missing products is ongoing and is expected to be completed by tomorrow, 4 September.
We apologise for any inconvenience this may cause.

Infrastructure maintenance activities are scheduled on Wednesday, 5 September 2018 from 07:00 UTC to 16:00 UTC and Thursday, 6 September 2018 from 07:00 UTC to 10:00 UTC.
During the maintenance window the publication of new products will be temporarily delayed as follows:

The publication backlog will be gradually recovered during the hours following the maintenance completion.

We apologize for any inconvenience caused.

Collaborative Data Hub Node 1 unscheduled downtimes 31-August-2018

31 Aug 2018

Collaborative users are informed that an unscheduled service downtime occurred on access node 1 from 00:55 UTC to 01:30 UTC of the 31 August 2018.
At 08:50 UTC another downtime has started and it is currently under resolution. The service will be restored at 09:45 UTC. Products publication is delayed. Backlog is currently in the process of being recovered.
Root cause is under investigation.
Our apologies for the inconvenience caused.

Sentinel-3A data unavailability on 22 August 2018

29 Aug 2018

Due to a ground segment anomaly that occurred on 22 August 2018 at approximately 13:00 UTC, all Sentinel-3A NRT/NTC/STC L1 and L2 user data covering a sensing time from 11:23 UTC to 13:04 UTC are unavailable.
